RAILWAY-CAR TRUCK.

Specification of Letters Patent.

To all )whom t may concern:

Be it known that I, WILLIAM P. BETTEN DORP, a citizen of the UnitedStates, residing `which the body may be readily lifted, or

I- `tilted to one side or the other while supported thereby. i l

The object of my invention is to enable the body of the car to be thusmanipulated without disconnecting or uncoupling the running gear of theremainder of the cars l, of the train.

" Another object of my invention is to provide atruck body whichcombines the truckl bolster, the draft-rigging support, thejourofmy'improved truck. Fig. 2.is a side ele` nals for the wheels andthe housing'for the cushioning elements for said Wheels in one' integralcasting. y

These and otherl advantages are obtained by the means hereinafter fullydescribed and as particularly pointed out in theclaims. In the drawings:-Figure 1 is a plan view vat-ion thereof. Fig. 3 is a longitudinalcentral section of the same. -Fig. 4-'is a transverse central section.`Fig. 5 is a detail view showing one cornerof the truck-frame insect-ion.

In the drawings A represents al rectangular-,frame which is, preferably,cast inone piece'of metal, and has the edges thereof flanged downward.At the center of length of each side thereof, frame A is provided withside extensions a, a, that enter between the wheels B, B, of the truckand practically serve as the ends of an integral truck-bolster portion.Generally speaklng the plane of the upper surface of said frame A ist-he same throughout, except atits center of length and width it isprovided with a sunken` female central bearing c, and at its ends overthe axle of the'car-wheels is shown to be stepped to a slightly higher"plane. Under each end-of truck-frame A, it is provided with dependingrectangular houslngs C, the outer sides of which are removed and adaptedto receive, rectangular journal'- b'oxes D for thejournals of thecar-axlesE. The portions of thesejournal-boxes Dw-thin housings C areadapted to have a limited vertical movement, and the inner walls of saidhousing have vertically elongated openings therein through which theaxle E extends and in which limited vertical play of the axles .isaccommodated. Immediately over these housings, a dome e is made, whichis, preferably, cylindrical and is of such interlor dimensions as toaccommodate carsprings f, whose upper ends bear against the closed topsof said domes and whose lower ends extend down through openings in thetop of the housing and rest upon the top of the journal-boxes D.

rlhe forward end of the truck-frame is, at its center of width providedwith a forwardly inclined hollow standard F, which is in longitudinalalinement with the pivotal center of-the truck, and terminates, at itsupper end, in a longitudinally elongated draft-rigging box G into whichthe shank or draw-bar of the car-couplers of the train,

is inserted below the plane of the body of' the car. This draft-riggingbox G, is rectangular and its forward open end reaches out in front ofthe transverse plane of the forward edge of the truck, and is reinforcedby a suitable marginal bead and on -top by transverse and longitudinalwalls or webs to enable it to resist the butllng of the upper ioning4element of the draft-rigging to be in-` serted therethrough. Thesecushions are arranged in tandem and a pin J is inserted between them,when the parts of the draftrigging are properly assembled. The head ofthis-pin 1s seated in a suitable counterV sunk openingin the top of thedraft-rigging Patented JulyQ, MM2.

box, and the lower end portion thereof passes w down through an apertureg in the bottom of the hollow draw-bar and into a suitablev opening inthe bottom of the draft-rigging box. PinJ is llattened laterally; thatis, at i right. angles to lthe draft 'ofthe' car, and

serves as an intermediate buliing element for the adjacent ends'-t ofthesprings.v The coul pler may be either hingedto or made integral with thedraw-bar, and may be of any design desired. yThe draw-bar will, underthe buiiing strain have a limited cushioned movement, before theshoulder 7c of the coupler cornes in contact withthe buffingcontrivances on the top of the forward end of the draft-rigging box.

At a point a suitable distance removed 10'` from the female centerbearing' of the truckframe, and located diametrically opposite thedraft-rigging elements, I provide said frame with a vertically disposedsocket m,

the principal portion of the length of which is below the plane of theupper surface of the truck-frame. This socket is adapted to receive oneof the hooked or down-turned ends, n, of a longitudinally disposedtie-rod M, which, as shown'in the drawings, may be used to tie the twotrucks of V each carl together. e

The web of the truck-frame, its transverse central portion, and its endsare provided with symmetrically disposed openings w, m', m2, ai", toreduce its weight, and the under- I side of said frame is provided witha series of symmetricallyV disposed 'downwardly projecting ribs or webs,that preferably, converge toward the center of the frame where theymerge into thei downwardly extending cylindrical walls of the femalecenter-bearing. The depth of these ribs or webs, prefl'erably, increasesas they extend from the outer edges of the truck-frame to the center ofthe same, and thus reinforce said frame on the principle of a truss,whose centeris designed to directly sustain the weight of the car andits load.

'What I claim as new is 1. A cast metal truck-frame for car-trucksextending from axle to axleand from wheel to'wheel and havin a femalecenter bearing'.I

and integral retaining devices for the jour!4 nale of said axles.

2. A cast metal truck-frame for car-trucks extending from axle to axleand from wheel A"to wheel and having integral retaining devices for theaxles at each corner and made wider inthe transverse plane of the spacebetween the wheels to provide an'integra'l truck-bolster.

A 3.. A cast metal truck-frame for car-.truckshaving an integral widenedtruck bolster tral bearing midway the length of said bolster portion,and a forwardly inclined integral standard.

7. A truck-frame for car-trucks ext-ending u in a horizontal plane fromaxle to axle between the wheels, having the under portions of its endsconstructed to receive and permit limited vertical play of the journalboxes of Y the wheels, having domes over said journal boxes to receivethe cushioning springs and Yhaving a widened central bolster portion.

from axle to axle, having the under portions of its ends constructed toreceive and permit limited vertical play of the journal boxes of thewheels, having domes over said journal boxes to receive the cushioning,springs, having a widened central bolster portion, and having anintegral draft rigging support. 10. A car-truck comprising a cast metaltrpck-frame extending from axle to axle and from wheel to wheel havingan integral center plate, andan opening therein in longitudinalalinementwith the pivot thereof, and a connecting rod .for connecting one cartruck of a car to another, the ends of which are bent downward andadapted to enter said opening.

11. A cast metal truckframe for car trucks extending from axle to axleand from wheel to wheel and a connecting rod one end of which is adaptedto be attached to said truck frame'at apoint to the rear of and in A'longitudinal alinement with its pivot.

12.

within the same.

14. AI horizontally disposed cast. metal truck frame for car-trucksextending from axle to axle between the wheels having the under portionsof its ends so constructed as to receive and permit limited verticalplay of the journal boxes of the wheels and having integral domes oversaid journal-boxes extending abovethe upper surface of the truck-frameto receive the cushioning springs. y 15. A cast steel truck-frame forcar-trucks extending from axle to axle between the 5 wheels and havingan integral cored out neck arising, substantially, from the center ofwidth of its forward part, and a draft-rigging box supported thereby.

16. A cartruck comprising a suitable -1`0 horizontally disposedtruck-frame arranged between the wheels and provided with acenter-bearing,alstandard arising from the foriward end of said frame, adraft-rigging box supported thereby, and a coupler havmg a tandemsprings within said hollow drawu bar, and a pin inserted through saidelon` gated openings between said springs andv having its ends securedinsaid draft-rigging.
